eminence APPARATUS.

To all whom 'it may concern.' g

Be it known that I, FRED H. DANIELS, of VVorceste'r, Worcestercounty,.Massachusetts, have invented a new and useful Improvementin(hargin'v Apparatus, of which the following is a fu,tion,ireference.being had to the accompanyfication, in which v l yFigure l is a plan view of a billet-charging apparatus embodying' myinvention; Fig. 2 is a longitudinal sectionof thesame; Fiv. 3 is an endelevation.

l/[y invention has relation to apparatusy for charging heatingfurnaces-and is de'- signed to provide apparatus of y'this' character-which will always be in condition Ato operate regardless of weatherconditions and which isl so arranged as topi-Ovide for the storage ofbillets or other blanks at the extreme end of the apparatus, which maybe outside of the building in the storage yard of the plant, thus savingroom in the building itself. y

Other objects and advantages of the invention will hereinafter appear.'

In the embodiment of my invention shown.

in the drawings, I have lindicated a'double width fur-nace'2, togetherwith two 'inde-l 4veyer, preferably a car 6,'running on the'.

tracks 7 arranged transversely. at thel outer end of the apparatus.

8 designates the pusher bar having hinged l to its outer end an arm 9,which, upon-thel forward stroke of the bar 8, is arranged' to engage thebillets on the car, as indicated in Fig. 2, and push the same on to theslideway 4, the arm being held rigid during this movement of the bar byits engagement with the shoulder 10 thereon. During the reverse movementof the bar, the a'rin swings out of the way and slides over the'bille'tsuntil'the end of the row is reached. The bar is actuated by means of arack 11, secured thereto and engaged by a pinion 12, on a shaft 13,

are su ported from "the vfurnaoe'2, as in dicate at 19. The pinion 12also forms fa' su port for 'the bar, and ai roller 20 vjour-l -naledvonthe xed franiefmember 21 and bearing on' the .upper surface of the4bar,f. serves to take the upward .thrust yfrom-the gears.

The operation will be readily understood#` When' the motor 15 lisoperated, the arm 8 isreciprocated and Aeach forward stroke pushesaseries of billets from. `the car 6 on to the sl'idewayJl, at the sametime moving the entire series of billets continuously alon the slidewayand through the furnace whic j is of the continuous type. During thereverse movement of the pusherbar, the arlnv 9 slides freely over thesupports in theman-,f-

ner before described. y 4 l i :The shafts of the two motors may becon-4nected, if desired, as shown in' Fig. 1.V The advantage of connectingthe shafts ofthe two motors .in this 'manner is that the two'f pushersmay be made to act- `as one, in'qcase long` b1lletsare, charged luto thefurnace,

that is to say, the 'two racks will travel tol' gether in the samedirection'. and at the 'same time, and thefbillet which extends 'clear'-across the `furnace, or which is twice. the length of the billetsordinarily used, can be charged through the furnace.

The 'advantages of my invention will be apparent to those skilled intheart. The,

customary way heretofore of charging a' bilp let-heating furnace hasbeen by means of af' hydraulically-operated pusher, which forces anumbero billets into the'furnace from a car placed between it and theusher or from a stationary support on whic layers of bil. lets aresuccessively placed, by means of a suitable overheadicrane. The seriousdisadvantage of this .arrangement is that 1n vcold weather), the pusher1s liable to be rendered; inoperative, dueto freezing lof the f water..As the furnaces should be placed4 Y inside the buildinglbut as near theoutside 4 e, the useof a hydraulic billet yard as poss pusher `of thiscommon type necessitates either running the track for the carsinto.

lt Will be obvious that various changes may be made in the details oflconstruction andarrangement of the several parts, Without departingfrom the spirit and scope of my invention,"as defined in the appendedclaims.v Flhus, the manner of supporting the pusher bar may be changed,any suitable arrangement .of actuating gearing between the motor and thepusher har may be lemployed, and various other changes may be made. Thepusher bar and arm or linger may also bel actuated Aby other means, suchas a hydraulio or pneumatic cylinder placedover the billet slidevvay,and inside the building. lnstead of employing the apparatus with adouble Width furnace, tivo single Width furnaces maybe used whenpreferred but to move one charging mechanism being employed with eachfurnace in such case, andA the chargin mechanisms may be connected so inunison or not is desired.
